Developments In The Barcode Tags And Scanners Industry
The emergence of technology in transportation, communication, computer and entertainment has long been observed by people. And with the development of these high technology inventions, the need for safety and security arise. Technology has also seen this need which led to the development of barcode tags and scanners. A barcode is a representation of information. It is readable by a machine called scanner. The barcode is printed on a small piece of paper called tags.
The barcodes are printed with dark ink usually with a white background. This is done to create a high and low reflectance allowing the scanner to convert the code into binary language. This way, the scanner can read the code. In the past, barcodes were stored in the spaces of paralleled lines. But technology made it possible to store these data in different shapes and patterns.
Barcodes now have become an important part of peopleâ€™s lives. They have entered the business world as diverse as transportation and telecommunication. Businessmen find barcodes the most cost-effective aspect pf business and management. Barcode and scanning system uses several symbols to make the conversion of bar codes into the computer's language making it possible for scanners to read the code. Some most common symbols are code 39 which is now used for data security. This is an efficient way of securing the data as it has the self-checking property that out of 70 million characters scanned, only one error is expected. UPC, another most common symbol is now found on non-food goods sold in the market. This is used for a more efficient and easier price look up without increasing the printing cost. 2of 5 Code was also created for warehouse inventory handling and airline ticketing. Codabar is used to process airway bills and are now very common in freight forwarding companies and custom brokers.
Plessey Code is commonly used in grocery stores. This type of code is the one that are put in items and the cashier or teller scans for price look up and computation of the bill and Code 11 is very effective for telecommunication components labeling. With the development of different symbols for barcodes comes the development of barcode readers or scanners. Barcodes transmit information and the transmission depends on how the bars and spaces in a code are arranged. The barcode scanners are responsible in scanning and reading the information converting it into the binary language then transmitting it to the computer attached to it. Using the light detector attached to the scanner, the amount of reflection is then converted into an analog pattern. Different kinds of readable machines or scanners have been developed to make the scanning more efficient and accurate. These scanners come in a variety of sizes, shapes, and prices. Checkout scanner is the most commonly used. These are found in many supermarkets.
Light pen is also one of the most commonly used as it is portable and cheap. Another type is the barcode slot reader which is used to scan moving codes. This is used in airports to scan the codes attached to the luggage. Laser barcode readers use the laser technology. It deals with light in small powerful beams. These readers can be used in freight forwarding to track the progress of shipment. It is one of the most expensive scanners and many freight forwarding companies and custom brokers invest on this to ensure an effective and safe transporting of goods from one place to another. With the latest technology in security and safety, barcodes and scanners are now part of peopleâ€™s lives. Numerous benefits and advantages are seen with the use of these security and safety devices. Nowadays, almost all stores such as grocery, department stores and merchandisers use the barcode systems.
This is very helpful to track prices without having confusion especially with large purchases. It also helps in making transactions faster and more efficient. In big offices and companies, document management is a management now being used to manage the hundreds of documents. Several tools used in the management model use sheets with barcodes in separating the documents. Custom brokers and freight forwarding companies use barcodes to track the shipment and movement of items. Biological science now makes use of bar coding technology to track reproduction of insects. Airlines, stadiums, theatres, car rental companies, and other establishments that give tickets have barcodes on the tickets to verify the validity before allowing the guests to enter. In the recent years, the decline in production of many factories and manufactories has been seen. This was due to less effective, costly and less efficient manual labor.
